SPEVA automatic sample purification and concentration instrument Introduction: SPEVA adopts an integrated design of solid-phase extraction and concentration, automatically completing solid-phase extraction steps such as activation, sample loading, elution, drying, and elution, while simultaneously performing online concentration and re-dissolution of the eluate and re-chromatography. No human intervention is required during this process, freeing up labor and protecting the health of experimental personnel. SPEVA features multiple sample preparation modes, easily handling sample pretreatment in various fields, such as pesticide and veterinary drug residue detection in food, organic pollutant enrichment in large-volume environmental water samples, and toxicant detection in viscous samples such as blood and urine. Innovative pump valves and compact structural design make it characterized by high throughput, fast speed, and accurate results, significantly enhancing the laboratory's detection capabilities. Technical features: 1. Integrated design of enrichment, purification, and concentration The same host can automatically and continuously complete the entire process of solid-phase extraction and nitrogen blowing concentration in batch (column activation, sample loading, elution, drying, elution, stepwise collection, batch concentration, and concentration and volumetric adjustment) 2. Multiple sample making modes to meet different needs Facing different sample matrices, various sample preparation modes can be chosen to easily handle samples from diverse fields such as large-volume environmental water samples, fruits and vegetables, fish, shrimp, poultry meat, blood, urine, traditional Chinese medicine, and Western medicine 3. High-throughput, batch processing Number of samples for automatic solid-phase processing: ≥48, with ≥40 rinsing positions available simultaneously. Number of samples automatically concentrated after solid-phase extraction on the same main unit: ≥48 4. Precise flow rate control, accurate experimental results Utilizing a flow system equipped with a high-precision syringe pump and a column insert rod, the column insert rod directly fits the packing material, leaving no solvent retention space. The set push rate of the high-precision syringe pump is the flow rate through the column, which is not affected by the characteristics of the sample itself, ensuring the accuracy of experimental results 5. Excellent chemical properties All sample contact tubing does not introduce impurities or adsorption, ensuring that the theoretical recovery rate can be achieved Sample pump specifications: >8 sets of 10mL high-precision syringe pumps. Sample loading flow rate: >100mL/min. Upgradable tip mode function: TIP tip loading mode, automatically using >48-position 1m ITIP tips to complete sample loading without cross-contamination. 6. Stable pump valves and multi-axis structure, with no redundant actions Utilizing an injection pump and multi-way valve, it boasts extremely high pressure resistance, significantly enhancing the efficiency of processing large-volume samples The independent multi-axis structure allows each module to operate independently, eliminating unnecessary mechanical waiting time 7. Intelligent software interaction, with real-time monitoring of the operation process Graphical software interface, large screen display, intuitive and easy-to-understand method interface The program settings are flexible and adaptable, allowing for real-time changes to methods and sequences during operation, and enabling the simultaneous execution of multiple methods The instrument's operating status is displayed in real-time, and automatic production monitoring logs are generated for convenient recording and querying It features solvent warning and automatic identification of sample racks, collection racks, and column racks 8. Patented design of variable diameter nitrogen blowing needle The high-strength internal and external needle design ensures that the nitrogen-blowing needle remains centered in the sample tube at all times The nitrogen blowing needles exhibit good uniformity in inner diameter, ensuring consistent air flow rate for each needle 9. Safe and reliable Closed design with an independent exhaust system to prevent solvent evaporation and contamination of the laboratory Transparent cover allows for real-time observation of the sample-making process, enabling adjustments to the operation method at any time Floor-standing design, compact structure, no need for a fume hood
